Forarbejdertil en Norsk Lovmosfloraav I. Hagen. (Det.Kgl. Videnskabers 
Selskabs Skrifter. 1907. No. 13) Trondhjem, Norway, 1 908. 
Part I. Orthotrichaceae. 
This pamphlet of 100 pages will be interesting in many ways to those 
North American moss students who are able to read Norwegian, owing to 
the large number of species common to the two countries. The genera 
treated are: Zygodon (2 spp.), Ulota (9 spp.), Orthotrichum (37 spp.), 
Stroemia (2 spp.), and Aulacomitrmm (1 sp.). Latin keys are given under 
each genus, as well as Latin diagnoses of all new forms. The most of the 
text, however, is in Norwegian and confined to notes upon the variations, 
historical treatment, and other points of interest connected with each species. 
A full list of localities are given. Detailed descriptions are given for all 
parts of Orthotrichum abbreviatum Gronv. to which O. Sardagnae Vent, is 
reduced. The following new combinations are made: Zygodon viridissimus 
(Dicks.) R. Br. , var. Stirtoni (Schimp ) Hag. {Z. Stirtoni Schimp.); Aula, 
comitrium Daviesii Dicks,) Hag. ( G lypho m itri um Daviesii Brid. ). The 
following are described as new: Ulota Drummondii (H & G.) Brid., var. 
anceps Hagen; Orthotrichum nudum Dicks., var. norvegica Hagen; C. 
Killiasii Muell.-Hal. , var, transitoria Hagen The genus Stroemia is pro- 
posed for the section Obtusifolia of Orthotrichum, comprising the species S. 
gymnostoma (Bruch) Hagen, and S. obtusifolia (Schrad.) Hagen. 
An index of the genera and species mentioned concludes the work. 
Edward B. Chamberlain. 
A second pamphlet of one hundred and twenty- two pages with the above 
title, under date 1908, No. 9, was received in June of this year. It contains 
the following sections : II. Meeseaceae, III. Georgiaceae, IV. Disceliaceae, 
V. Neckeraceae, VI. Pseudoleskeaceae, VII. Thuidiaceae, and VIII. Leskea- 
ceae. More of the text is in French than in the first part, reviewed by Mr. 
Chamberlain, the change being made at the suggestion of M. Theriot, who 
has also read the proof for this portion. 
As stated in the preface of the first part, it is the intention of Dr. Hagen 
to issue a series of papers on the mossflora of Norway based on a study of the 
material in the Herbarium of the Natural History Museum of Trondhjem, of 
which he is Director. There is a large collection, and will require a vast 
amount of work with the microscope, and revision of critical groups, so it is 
evident that the work will take a number of years to accomplish. It is hoped 
to issue at least one pamphlet each year.
